Summary
Existing TLC systems for the separation of dianthrone glycosides (sennosides) and anthraquinone glycosides were found unsatisfactory. Separation of these two groups of glycosides was achieved using a conventional TLC development tank and also in a modern VARIO-KS-Chamber at a relative humidity of 32%. The separation in a VARIO-KS-Chamber was superior.
